Megger RCD200 Loop Impedance and RCD Tester

Overview

The Megger RCD200 is a professional loop impedance and residual current device (RCD) tester for verifying the safety of low-voltage electrical installations. It carries out three-wire, non-trip loop impedance measurement from 0.01 Ω to 2 kΩ, calculates prospective fault current, and tests RCDs across the common rated sensitivities – giving electricians the core measurements needed for periodic inspection and commissioning.

As well as RCD trip-time and no-trip (ramp) tests at 10, 30, 100, 300 and 500 mA, the RCD200 measures voltage, frequency and touch voltage, and displays prospective fault current up to 19.9 kA. A rugged IP54 case, CAT III 300 V rating and up to 2000 tests per set of batteries make it a dependable everyday instrument for installation testing.
